METAL-PLATE CATCHER,BRAND.ER, AND POLISHING MACHINE.

srncrrrca'rrou' formingpart of Letters Patent N 620,685, dated February21, 1899.- Application filed July 16,1898. Serial 110.; 686,148. (Noman.

To all whom it may cancer-m2 Be it known that I, J OHN E. Benson,residing at Martins Ferry, in the county of Belmont and State of Ohio,have invented a new and Improved Metal-Plate Catcher, Brander, andPolishing Machine, of which the following is a specification.

This invention is in the nature of an improved mechanism comprehending anovel construction and arrangement of parts whereby metal plates afterreceiving an external coating can be practically and automaticallyhandled as they leave the hands of the dipper and be subjected tosuccessive and continuous actions, whereby the plate .without the aid ofmanual labor is first caught, branded, cleaned, and then polished in aneffective, quick, and economical manner.

In its more specific character this invention embodies, in combination,a novel form of catcher, brander, and polishing mechan: ism working inharmony with the coating mechanism and in such close relation theretothat the plates as they are drawn from the coating or tinning vat properare moved into engagement with the catcher, then caught by supplementalcombined catcher and cleaner rolls, and after being cleaned of the bulkof oil or grease deposited thereon automatically delivered onto adelivery or carrying mechanism, which feeds the partially cleaned platethrough a novel form of branning mechanism having an interdependentconnection and operation with the catcher or main delivery andthesupplemental catcher and cleaning mechanisms, additionalplateengaging means, in the nature of polishing and duster rolls,beingalso provided and working in unison with the aforesaid mechanism foreifecting the final polishing and cleaning operation of the plate.

Another and important feature of this invention is the employment, inconnection with the means for simultaneously carrying and cleaning theplate, of an air-blast to engage the plate as it is carried from thecoating-vat,'whereby to effect a quick and positive set of the .coatingmetal to prevent the danger of scratching or other mutilation on theouter or tin coating of the plate as it passes through the several stepsconstituting the branning and cleaning operation of the completemachine.

In its subordinate features this invention comprises certain details ofconstruction and novel combination of parts, such as will be firstdescribed in detail and then be specifically pointed out in the appendedclai'ms','reference being had to the accompanying drawings, in which- 7Figure 1 is a view of one end of the complete machine, the catching ordelivery mechanism being shown in section and the supplemental polishingand branding mechanism in end View. Fig. 2 is a side elevation of thebranning and supplemental polishing and cleaning mechanism, the catcheror initial-delivery mechanism being shown in end elevation. Fig. 3 is adetail longitudinal section of the branning mechanism. Fig. 4 is adetail sectional elevation taken practically on the line 4 4 of Figl 1.Fig. 5 is a detail horizontal section taken on the line 5 5 of Fig. 3.

In its general construction my invention comprises a supplemental tinreceiving and feeding means in the nature of a set of combined catcherand cleaning rolls, which are arranged in close relation to a maincatcher or delivery mechanism located within the tinvat and having itsreceiving end so disposed that the dipper after properly manipulatingthe plate in the coating-vat canconveniently deliver the same into thereceiving end of the main catcher mechanism ,after which the plate iscarried through such mechanism to the supplemental combined catcherand-cleaner rolls, and after passing'through the same deflected bysuitable devices and deposited on a slide, which carries it onto asupplemental carrier, which delivers the plate to the branningmechanism, from whence it passes through supplemental duster andpolishing meansv and is finally discharged from the table intoa suitablereceiver. In passing from the supplemental combined catcher and cleanerrolls the plate is subjected to an air-blast from one or both sides,which serves to quickly cool the plate and causes the coating materialto become firmly set thereon, and thereby avoid the danger of the platebecoming scratched or otherwise mutilated as it passes througiftheseveral operations of cleaning and polishing.

In the practical application of my invention I employ my improvements inconnection with any ordinary form of initial catcher and deliveringmechanism, which will carry the plate as it leaves the dipper throughthe tinpot and oil to a. discharging-point.

In the drawings I have illustrated an initialcatcher mechanismcomprising a housing 2, the mouth or end 2 of which preferably opensinto the coating portion 3 of the vat, whereby to facilitate the passingof the coated plate from the vat to the first set of catcher-rolls.

The combined initial catcher and delivery mechanism, the detailconstruction of which, per se, forms-no part of my invention, maycomprise a frame consisting of two side members 4, connected at theupper end by transverse brace-rods 4, which have at one end asupportinglip 4 and at the other a hangerbracket 4, adapted to besupported on a sustaining rod 5, passed transversely on the housing 2,by means of which and the memher 4', which engage and are supported onthe ledge 2 of the housing, the initial catcher and deliverymechanism issuitably and rigidly su ported within the housing.

A B indicate a series of initial-catcher rolls which are so disposedthat the plate as it is carried from the receiving end to the dischargegradually assumes a vertical position, whereby to properly engage thesupplemental catcher and cleaner rolls, presently referred to, it beingunderstood that to facilitate the travel of the plate through theinitial-catcher mechanism suitable guides 7 are provided, as v shown.

The supplemental combined catcher and cleaner rolls D are mounted in asuitable housing 12, adapted to be detachably but firmly supported uponthe housing 2. These rolls may consist of a solid core and outergripping and cleaning portions, which may be of a solid nature havingtransverse grooves whereby to effectively grip the plate as it is drawntherethrough. I prefer, however, to form the exterior faces of the rollsD of polished steel, as the danger of'injury to the plates as they aredrawn therethrough is thereby reduced to a minimum.

Toprovide for cleaning the plate of the bulk of. the oil and greaseafter it leaves the pots 2, scraper-shoes 8 are provided, which areyieldingly held against the face of the rolls D in such manner that theywill scrape ofi any oil or other greasy substance which might adhere tothe rolls, and thereby leave the face of the rolls engaging the plate asclean as possible to eifect a more positive gripping action of the plateand at the same time remove any deposit of oil gathered on the rollsfrom the plate as it passes therethrough and cause 'the same to dropback into the pot 2. g

7. indicates a guide for leading the plate from the uppermost set ofrolls 0 of the initiabcatcher mechanism to the rolls D.

To quickly set the coating material on the plate as it leaves the pot, Iprovide air-blast pipes 14 14, which in practice are so arrangedrelatively to the rolls D as to eject a strong current of air onto theplate, on both faces thereof, it being understood that the blast can beproduced by a suitable fan operated from the drive-gear which operatesthe tinning mechanism, from which gear the catcher may also be operatedby suitable gear connections, .such rolls having gears a b c d, asindicated in dotted lines'in Fig. 1. The blastpipes are extended atconvenient points outside of the tinning-pot and provided with cutofivalves, their discharge ends terminating in distributing-pipes 11,having jet-openings 11.

Upon the upper end frame 12, in line with the rolls D, are disposedadjustable deflectors 13, one being arranged at each end of the rolls Dand so disposed that the plate as it is carried up from the rolls D inthe direction indicated by dotted lines in Fig. 1 will engage the saiddeflector members 13 and be thereby caused to tip over onto an inclinechute 14", which extends forward over a delivery mechanism forming apart of the branning and supplemental polishing mechanisms, theconstruction of which is best shown in Figs. 2 and 3 and consisting ofrolls 15, as indicated in the drawings, it being obvious, however, thatinstead of being a series of rolls the same may be in the nature of anendless vbelt to form a horizontal rest and delivery for feeding theplate to the branning mechanism, which will be presently more fullydescribed. From the foregoing it will be observed that the plates asthey leave the dipper are drawn up. through the tin and oil pot by therolls A B O and delivered vertically endwise to the rolls D, it beingunderstood that as the plate is drawn up fromthe rolls the oil or greaseadhering thereto will drop back into the pot, and such oil or grease asmay adhere to the upper peripheral faces of the rolls will be scrapedoff by the shoes 8 and will drop back into the pot, thereby keeping theplate-engaging portions of the rolls practically free of oil or grease,as heretofore stated.

Referring now more particularly to Figs. 2 and 3, it will be observedthat the deliveryrolls' 15 'are journaled in the same horizontal planeand are arranged at one side of the brander, which is located at a pointbetween .such rolls 15 and the final dusting and polishing rolls 17 1819. The brander consists of a casing 20, closed at the top and having ahopper 21, discharging into a cylindrical receiving-chamber 22, theinner or discharge end 22 of which receives the upper peripheral edge ofthe upper one of a pair of combined branding and feed rolls-25, thelower one of which is held in the same horizontal plane as thefeed-rolls 15, an additional pair of feedrolls 27 27" being disposed ateach side of the branding-rolls 25 25 and in line with the open ings 26in the sides of the branding-casing,

' through one of which the plate is drawn and which as it leaves thebrander devices moves through the other opening and engages thev dusterand polishing rolls, presently again referred to.

To facilitate the removal of any foreign substance onthe face of theplate as it enters the brander and also to assist in brushing it'as theplate leaves the brander, and a still further and more essential objectto prevent the bran-dust flying out of the brander in the tinning-room,the openings 26 have detachable members 28, carrying brushes 28*,whichwhen fitted-in an operative position are held in close contact and serveto practically close the openings 26 against the discharge of any of thebran-dust within the brander-casing.

In the practical arrangement of the several sets of rolls within thebrander-casing I prefer that the first and third sets of rolls 27 27 beformed of solid shafts having gum bands or rings around it, whereby therolls will have practically acollared peripheral face to prevent suchrolls from choking or clogging up with bran or other absorbent beingused. The center rolls 25 consist of wooden cores covered with sheepskinor felt, which will serve to rub .the plate with absorbent and also topolish the plate as it is drawn therethrough.

To provide for a uniform and regular dusting of the bran on the plate asit passes from the brander, the cylinder or collector chamber 22 has arotary distributor, consisting of a solid roll 29, havinglongitudinally-directed spirally-arranged peripheral grooves 29*,suchroll 29 in practice being held in close relation with the upper face ofthe upper brander-roll 25, as best shown in Fig. 3.

30 indicates a trough held under the branderrolls, which may, ifdesired, have an opening at one of its ends (not shown).to facilitatethe removal of bran or other absorbent-material collections, and thecasing proper may also have openings for this purpose.

After the plate passes through the brander it is engaged by the rolls 1718 19 and subjected to a dusting and polishing action, from which itpasses onto a suitableadjustable chute or incline onto a receiving tableor plain smooth or yielding cylinders, are driven holder. To facilitatethe polishing and dusting action, the rolls 18 have a felt or sheep-'skin cover, and such rolls 18, together with the brander-rolls 25 andthe brander-feeder roll 29, are rotated at a speed greater than thefeed-rolls which carry the plate forward, whereby to effect a positiveand effective branding and polishing action on the plate as it travelsthrough the several sets of differentially-rotatedrollers.

In practice the carrying-rolls, which have at a comparatively slow.speed, as are also the feed-rolls of the brander and the polishing andduster mechanism, while the polish-' ing-rolls of the brander and of theduster devices are driven at a greater speed.

It will be observed that the operation of the machine is substantiallyautomatic, and

whatever manual labor may be necessary in connection therewith can be ofa very unskilled character. 2

The movementof the. plate from the time it leaves the tin-pot until itis discharged on the adjustable table at the duster and polishing end'ofthe machine is entirely continuous, the capacity of the entire machinedepending entirely on the feed of the plate to the first catcher ortinnef roll A by the dipper and the speed of the several partsconstituting the complete machine.

I Having thus described my invention, what I claim, and desire to secureby Letters Patent, is
